Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically a lithium battery charging / discharging power failure alarm device. Background Technology

[0002] As is well known, lithium batteries are batteries that use lithium metal or lithium alloy as the anode material and a non-aqueous electrolyte solution. The Class III medical product standard requires that the product have a power outage alarm function.

[0003] The power failure alarm function is designed to activate when the product is powered on, in standby, or in treatment mode, and the mains power supply stops or becomes abnormal due to a power outage or malfunction. The power failure alarm function is manifested by the corresponding alarm light illuminating and the corresponding alarm sound emitting.

[0004] Because the product requires an independent power supply to function as a power failure alarm when there is no power source available, the product's power failure alarm function requires an independent power source.

[0005] Independent power supplies should be selected from rechargeable, small-sized batteries with a certain capacity. However, battery charging requires corresponding charging voltage and current based on the characteristics of the battery materials. Battery discharging, i.e., the battery output voltage and current, will change with the size of its own charge, which does not meet the power supply requirements of power failure alarm. Therefore, a charging and discharging management scheme needs to be designed for the battery to provide power for the power failure alarm.

[0006] Existing lithium batteries cannot detect power outages during use. When the battery itself loses power, no alarm is triggered, reducing the convenience of using lithium batteries. Therefore, we propose a lithium battery charging and discharging power outage alarm device to solve the above-mentioned problems. Summary of the Invention

[0007] The purpose of this invention is to provide a lithium battery charging / discharging power failure alarm device to solve the problems mentioned in the background art.

The positioning hinge members are installed on one side wall of the clamping plate.

[0018] As a further embodiment of this utility model: both the first spring and the second spring are sleeved on the outside of the fixed rod.

[0019] As a further embodiment of this utility model: a set of heat dissipation holes is provided on both side walls of the box, a set of dustproof nets is provided on one side of each set of heat dissipation holes, a set of mounting frames is provided on the outer side of each set of dustproof nets, a set of mounting blocks is provided at the four corners of the outer walls of each set of mounting frames, a set of mounting bolts is provided on each set of mounting blocks, and the set of mounting bolts is connected to the box.

[0020] As a further improvement of this utility model: a display panel is provided on the front wall of the box, and multiple sets of connecting lines are provided on the back wall of the box.

[0021] As a further embodiment of this utility model: the power failure alarm detection structure includes an AC / DC power adapter, a DC / DC converter circuit 1, a DC / DC converter circuit 2, a power failure alarm detection circuit, a power failure alarm circuit, and a battery charging and discharging circuit for the IP5206 chip. The AC / DC power adapter converts 220VAC to 12V output to power the product; the DC / DC converter circuit 1 converts 12VAC to 5.5V output to power the product control circuit and the power failure alarm detection circuit; the DC / DC converter circuit 2 converts 12VAC to 5V output to power the battery charging and discharging circuit for the IP5206 chip; the power failure alarm detection circuit detects the 12V signal and 5.5V signal status to determine whether to activate the power failure alarm.

[0024] Based on the IP5206 mobile power SOC chip, it includes both lithium battery charging and discharge boosting functions, requiring very few external components and effectively reducing the overall solution size and BOM cost.

[0025] The IP5206 chip has an output current detection function. When the product is powered off normally and no power failure alarm is triggered, the IP5206 chip automatically enters a sleep state, and the static current drops to 50uA, thus maintaining the lithium battery power for a long time.

[0035] In one embodiment, such as Figures 1-8 As shown, the lithium battery charging / discharging power failure alarm device includes:

[0036] Box 1;

[0037] Box cover 2, which is set on the upper end face of box body 1;

[0038] Handle 3 is located on the upper surface of the box cover 2;

[0039] The battery body 4 is located on the inner wall at the bottom of the housing 1;

[0040] A power failure alarm component is used to monitor the power failure of the battery body 4 and is installed on the battery body 4. The power failure alarm component includes a power failure alarm detection structure 5, which is connected to the upper surface of the battery body 4 and is connected to the battery body 4. A display component is also provided on the housing 1. The display component includes a power failure alarm panel 6, which is installed on the front wall of the housing 1. A sound alarm 7 is provided on the power failure alarm panel 6, and a light alarm 8 is provided on one side of the sound alarm 7. The light alarm 8 is installed on the power failure alarm panel 6. The power failure alarm detection structure 5, the sound alarm 7, the light alarm 8, and the battery body 4 are electrically connected.

[0041] Specifically, during operation, the battery body 4 can be detected for power failure by the power failure alarm detection structure 5. When a power failure occurs, the power failure alarm detection structure 5 transmits a signal to the power failure alarm panel 6, enabling the sound alarm 7 and light alarm 8 to emit sound and light, thereby alerting staff and facilitating their inspection. By setting up a power failure alarm component consisting of the power failure alarm detection structure 5 and the display, the battery body 4 can be detected for power failure. When the battery body 4 experiences a power failure, the sound alarm 7 and light alarm 8 will sound an alarm, making it convenient for staff to inspect the battery body 4.

[0042] The power failure alarm detection structure 5 includes a power adapter AC / DC power adapter, a DC / DC converter circuit 1, a DC / DC converter circuit 2, a power failure alarm detection circuit, a power failure alarm circuit, and a battery charging and discharging circuit with chip IP5206.

[0043] a) AC / DC power adapter, which converts 220VAC to 12V output to power the product;

[0044] b) DC / DC converter circuit 1 converts 12VAC to 5.5V output to power the product control circuit and power failure alarm detection circuit;

[0045] c) DC / DC converter circuit 2 converts 12VAC into 5V output to power the IP5206 battery charging and discharging circuit.

[0046] d) The power failure alarm detection circuit detects the status of the 12V and 5.5V signals to determine whether to activate the power failure alarm. The condition for activating the power failure alarm is that the circuit detects the disappearance of the 12V signal and the presence of the 5.5V signal.

[0047] The product has three power failure modes. Normal power failure mode 1 is when the power button is turned off, the 5.5V signal disappears, the AC / DC power adapter outputs a 12V signal, and the power failure alarm will not be activated.

[0048] Normal power failure method 2: First, turn off the power button. After the 5.5V signal disappears, disconnect the 220VAC input of the AC / DC power adapter. If the 12V signal disappears then, the power failure alarm will not be activated.

[0049] Abnormal power failure alarm: If the AC / DC power adapter 220VAC input is disconnected or the AC / DC power adapter is disconnected from the product connection plug, and the power button is in the closed state, the 12V signal will disappear first. Since there is an output capacitor in DC / DC converter circuit 1, the 5.5V signal will disappear after a delay. This meets the conditions for activating the power failure alarm and will start the power failure alarm.

[0050] e) The power failure alarm circuit includes indicator light drive circuit, indicator light, horn drive circuit and horn, etc.

[0051] f) Battery charging and discharging circuit of chip IP5206 (e.g.) Figure 8 (As shown)

[0052] When the product is in normal power-on state, the output voltage of DC / DC converter circuit 1 is 5.5V, and the output of the IP5206 battery charging and discharging circuit is 5.1V. Since 5.5V>5.1V, diode D2 is reverse cut off. Based on the output current of the IP5206 battery charging and discharging circuit being 0A, the IP5206 chip is in sleep state.

[0053] In normal power outage one and normal power outage two, the output voltage of DC / DC converter circuit 1 is 0V, and the IP5206 battery charging and discharging circuit outputs 5.1V voltage to power the power outage alarm circuit. However, since the power outage alarm circuit is not activated, the output current of the IP5206 battery charging and discharging circuit is very small, and the IP5206 chip enters a sleep state.

[0054] In the abnormal power failure alarm state, the power failure alarm function is activated, and the power failure alarm circuit is powered by the battery charging and discharging circuit of the IP5206 chip.

[0055] like Figures 1-3 As shown, a set of clamping plates 9 are provided on both sides of the battery body 4. A set of fixing frames 10 is provided on both sides of the two sets of clamping plates 9. The two sets of fixing frames 10 are respectively provided on the inner walls of both sides of the housing 1. A set of fixing rods 11 is provided on the inner walls of the two sets of fixing frames 10. Two sets of sliding hinges 12 are provided on the outer walls of the two sets of fixing rods 11. A set of first springs 13 is provided on one side of the two sets of sliding hinges 12. A second spring 14 is provided between the two sets of sliding hinges 12. A set of connecting rods 15 is hinged to one side of the two sets of sliding hinges 12. The other end of the two sets of connecting rods 15 Each is equipped with a set of positioning hinges 16, which are installed on one side wall of the clamping plate 9; the first spring 13 and the second spring 14 are both sleeved on the outside of the fixing rod 11; when the battery body 4 is installed, the two sets of clamping plates 9 can be squeezed, and the two sets of clamping plates 9 can drive the two sets of connecting rods 15 to move through the positioning hinges 16. The two sets of connecting rods 15 squeeze the first spring 13 and the second spring 14 through the sliding hinges 12, so that the two sets of clamping plates 9 are fixedly clamped on the outer side wall of the battery body 4, which facilitates the clamping and positioning of the battery body 4, thereby facilitating the disassembly and installation of the battery body 4.

[0056] like Figures 1-5As shown, each of the two side walls of the housing 1 has a set of heat dissipation holes 17. A dustproof mesh 18 is installed on one side of each set of heat dissipation holes 17. A mounting frame 19 is installed on the outer side of each set of dustproof mesh 18. A mounting block 20 is installed at each of the four corners of the outer wall of each mounting frame 19. A mounting bolt 21 is installed on each of the mounting blocks 20, and all mounting bolts 21 are connected to the housing 1. The heat dissipation holes 17 facilitate heat dissipation for the battery body 4 inside the housing 1. The dustproof mesh 18 prevents dust from entering the housing 1 through the heat dissipation holes 17. The mounting frames 19, mounting blocks 20, and mounting bolts 21 facilitate the installation and fixation of the dustproof mesh 18. A display panel 22 is installed on the front wall of the housing 1, and multiple connecting wires 23 are installed on the back wall of the housing 1. The display panel 22 displays the test results, and the connecting wires 23 facilitate the connection of the battery body 4 to external components.

[0057] The above embodiments disclose a lithium battery charging and discharging power failure alarm device. During operation, the battery body 4 can be detected by the power failure alarm detection structure 5. When a power failure occurs, the power failure alarm detection structure 5 transmits a signal to the power failure alarm panel 6, enabling the sound alarm 7 and light alarm 8 to emit sound and light, thereby reminding the staff and facilitating their inspection. At the same time, when the battery body 4 is installed, it can be clamped by pressing two sets of clamping plates 9. The two sets of clamping plates 9 drive two sets of connecting rods 15 to move through the positioning hinge 16. The two sets of connecting rods 15 press the first spring 13 and the second spring 14 through the sliding hinge 12, so that the two sets of clamping plates 9 are fixedly clamped on the outer wall of the battery body 4, which facilitates the clamping and positioning of the battery body 4, thereby facilitating the disassembly and installation of the battery body 4, which is quite practical.

[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
